Add the bacon, stock and mirepoix to an oven-safe pan, cover with foil and roast for 90 minutes. Then remove the bacon from the stock and allow to cool. Once cooled, portion into 4 portions and hold until re-cooking.
Add the stock, apple juice, bacon, onions, Cajun spice and collards to a stockpot and cook over medium-high heat until simmering. Then reduce the heat to low and cook until the greens are softened and the liquid has reduced to 2 cups, about 1 hour. After cooking, remove from the heat and hold warm.
For the tomato jam: During the collard process, in a small saucepot over medium heat, add the tomatoes, onions, horseradish, thyme, salt, cayenne, curry, white pepper and turmeric, and allow to cook for 75 minutes, stirring during the process. Once cooked, keep warm and tighten with a slurry if needed.
Once all three items are cooked, on an oven-safe pan, add the braised bacon pieces, top with tomato jam and heat under the broiler lightly browned, about 2 minutes. Once browned, portion the collards in a centered pile in a bowl, then top with the relish-broiled bacon and serve.
